Characteristics and possibilities of using Yutong aerated concrete blocks


Manufacturing technology

The production of YTONG aerated concrete on an industrial scale began in 1929. At first, the production of YTONG aerated concrete blocks was carried out only in Poland and Germany. Today they are produced in many countries around the world. To make aerated concrete, the following materials are used:


YTONG aerated concrete production

  • cement;
  • water;
  • sand;
  • lime;
  • calcium hydroxide;
  • aluminum paste.

The creation of many pores in the finished product occurs by adding aluminum paste to the solution. This substance reacts with calcium anhydrite and forms a large number of small bubbles.

Thanks to these pores, the finished products are lightweight compared to similar building materials. The presence of small voids in cellular concrete makes it possible to achieve low thermal conductivity of walls. A building constructed from such material will maintain an internal microclimate, regardless of the ambient temperature. This allows you to reduce heating costs during operation.

Description of aerated concrete

The German company (“Itong”) produces high-quality blocks for construction. All of them have high accuracy in sizing measurements. This will help in construction by speeding up the process, because the evenness of these blocks corresponds to the measurements. The error may be about one mm. And also their price is quite low. This allows you to build a house with minimal costs for materials. They have a large dimensional grid from which you can select a specific block for the construction of a foundation, house, partitions and even a balcony. Ytong is quite strong and durable.

Application of YTONG aerated concrete blocks

YTONG building blocks are widely used for the construction of residential and non-residential buildings. Due to their low weight, they are used for the construction of multi-story buildings. This way it is possible to reduce the pressure on the foundation. The characteristics of YTONG aerated concrete make it possible to construct various structural elements from it.


Where are YTONG blocks used?

Load-bearing walls of buildings

The material is characterized by high strength and geometric shapes. The outer walls of a building built from it will have low thermal conductivity. Smooth shapes reduce consumption of adhesive mixture.

Foundations and basements

When using it to build a foundation or basement, it is necessary to additionally carry out waterproofing, because the material is capable of absorbing moisture. At the same time, YTONG aerated concrete does not have the ability to absorb water.


Itong product range

Internal walls

The low weight of the wall blocks makes it possible to reduce the weight of the internal partition, thereby reducing the pressure on the floor of the apartment. This makes aerated concrete products in demand in the construction of buildings for various purposes.


YTONG products for interior walls and partitions

Jumpers and ceilings

The manufacturer YTONG produces several types of aerated concrete lintels for window and door openings. The plant also produces floor slabs. They are installed using a crane.

Manufacturing process

In its production, Itong uses environmentally friendly raw materials:

  • Sand.
  • Cement.
  • Water.
  • Aluminum paste.
  • Lime.

A mixture of cement and sand mixed with water foams through the chemical interaction of aluminum and lime. Hydrogen gas uniformly forms spherical closed pores in the material. The mass, increased fivefold in volume, is grasped and cut into structural parts with thin strings according to specified dimensions. The strength of the products is given in an autoclave, where they are steamed for 12 hours at a temperature of 190°C under a pressure of 12 atmospheres.

Characteristics of aerated concrete blocks

1. Durability. High load-bearing capacity with low weight is ensured by autoclave processing of the material. From Yutong, it is recommended to raise external enclosing structures no more than 20 m high and up to 5 floors, self-supporting walls no higher than 30 m, up to 9 levels.

2. Durability. Compliance with construction technologies ensures the operation of aerated concrete structures for more than 100 years.

3. Low moisture absorption. Does not absorb rain or melt water.

4. Geometric accuracy. Itong produces all parts according to exact dimensions (the error is no more than 0.8 mm).

5. Easy to process. Geometrically precise dimensions make it possible to lay perfectly even walls and partitions. Decorative finishing without preliminary leveling significantly reduces construction time. Their porous structure is easily amenable to any influence: sawed, milled, drilled with conventional tools, nails, staples and other fasteners are hammered into them without effort.

6. Sound insulation. The soft porous surface has a high ability to absorb and disperse sound waves, significantly reducing the noise level in the room.

7. Frost resistance. In the capillaries of the porous structure of aerated blocks, water, which increases in volume when freezing, expands without tearing the material.

8. Non-flammable. Non-flammable, autoclaved concrete elements can be used for the construction of buildings with temperatures on the insulating surface up to +400°C.

9. Vapor permeability. The ability to “breathe” prevents rotting, subsidence, and mold formation in the walls.

10. Seismic resistance. In regions with increased seismic activity, such buildings reduce the consequences of destruction from earthquakes and other natural disasters.

11. Thermal insulation. Itong autoclave blocks have the lowest heat penetration coefficient.

12. Energy efficiency. Due to low thermal conductivity, structures made from autoclaved parts are highly energy-saving.

13. Cost-effective. When constructing buildings made of aerated concrete, there is no need to use additional heat-insulating and sound-absorbing materials. The construction of thin walls reduces labor costs several times. There is no need for constant repair and restoration of durable structures.

Parts made from Yutong autoclaved concrete successfully combine the environmental friendliness of wood and the ease of processing with the strength of stone.

Types of products:

  • Wall blocks of different configurations.
  • Multifunctional U-shaped for enclosing structures and permanent formwork.
  • Reinforced lintels made of porous concrete for internal and external load-bearing walls.
  • Arc-shaped elements for the construction of smooth semicircular partitions, elegant bay windows and “snail” showers.
  • Aerated blocks for partitions are used when renovating premises with redevelopment of the internal space.
  • Prefabricated monolithic floors and stairs.

Description of Ytong features according to expert reviews:

  • Lightweight porous products greatly facilitate transportation, loading and unloading and installation work. Thanks to its low weight, the load on supporting structures and the base is reduced.
  • Frost resistance is at least one hundred cycles.
  • Yutong parts are produced systematically: they are selected and adjusted relative to each other.
  • The strength of autoclaved concrete at a temperature of +400°C increases by 80-85%. Ytong brand building materials are recommended for the installation of fire protection structures of any fire resistance class. Without igniting, without melting or deforming, the walls prevent smoke and the spread of fire.
  • The technology of thin-seam laying of wall gas blocks and the tongue-and-groove system, which replaces vertical seams, prevent active heat exchange between the environment and the microclimate inside the building.

Material characteristics


Comparison of fire resistance of concrete walls and structures made of Itong wall blocks

YTONG aerated concrete blocks are fire-resistant material. The material does not lose its properties within 4 hours of being in a fiery environment, the temperature of which is 400o C.

The frost resistance of the products is at the highest level. As a result, the reliability of aerated concrete structures used at low ambient temperatures is guaranteed.

The material has a thermal insulating effect. This is achieved due to the fact that there is air in the pores of aerated concrete, which, in turn, does not conduct heat well. A building made from such products remains cool on summer days and warm at sub-zero ambient temperatures.

Compound

The composition of the aerated concrete block is a mixture of:

  • slaked or unslaked crushed lime;
  • aluminum suspension and powder;
  • Portland cement;
  • quartz sand;
  • water approved by Gosstandart.

The basis of aerated concrete blocks is quartz sand. When aluminum is added to the mixture, its microelements, as a result of interaction with hydroxo groups, form aluminum oxide, as well as hydrogen, which gives the material porosity and turns it into aerated concrete.

Next, the aerated concrete block is placed in an autoclave oven, where it is compressed at a certain temperature and moisture level. As a result, thanks to crimping under the specified conditions, the final product is a new calcium silicate mineral that can withstand any chemical reactions.

What home owners say

“I am building a house from Yutong aerated concrete and I do not think that its cost is too high. Firstly, the sizes of the blocks are almost ideal, the laying proceeds quickly and even with pleasure. And the seams are no thicker than 2 mm. Secondly, I was attracted by the fact that everything in the system was thought out: I was able to take window purlins, ceilings, and U-shaped blocks in one place. And only there I found aerated concrete D400 class B2.5. However, the taste and color... I don’t impose my opinion on anyone. But what also gives confidence is that Yutong has been doing this since the 30s of the last century. The price of experience - who can measure it?

Dmitry, Ufa.

“The geometry is perfect, there are no words. The blocks are smooth, clean, neatly packed. And in general, the service is at the highest level, and I purchased the tools from them. Excellent product quality! But the shipping cost is not at all pleasing. And one more small inconvenience for buyers: the plant does not sell products directly. We will have to choose suppliers, and this matter should be taken very seriously.”

Vladimir Bolshakov, Moscow

“My review will be purely positive. We are building a house from Ytong blocks. Why one of them? It took a long time to choose, we heard enough of everything – both good and bad. But we decided to do it anyway, and now we don’t regret it. The products are first class. The appearance and size are beyond competition. But the final decision was still influenced by the company’s longevity in the market.”

Anastasia Zhdanova, Novosibirsk.

“I’m a builder myself, but I’ve never had to work with aerated concrete. So I asked people, read reviews on forums, and settled on Itong. In my opinion, this is the best that is within reach today. I’m happy with everything, but the delivery didn’t work out – I had to organize pick-up.”

Nikolay, Moscow.

“A neighbor was building a house from Yutong aerated concrete and asked me to help. We did everything according to video instructions, since we have little construction experience. They erected it quickly, the building has been standing for two winters without finishing. There are no cracks (most likely due to the fact that the foundation is slab - it protects well from water and from soil displacement), and in general it looks good.”

Roman, Samara.

“Good blocks, but... there is always some “But”. When I bought the 2000 kit, experts recommended that upon completion of construction, the walls should be covered with siding or plastered as quickly as possible (I also found something similar among consumer reviews on the Internet). Blocks absorb moisture and over time may begin to crack and crumble. The official website says that due to the nature of production, Itong gas blocks are slightly hygroscopic, but it’s better to be safe.”

Anatoly Solovyov, Kazan.
